Water - its properties and measuring - that's our mission for many years. We measure the most important parameters of water quality - be it drinking water or sewage water at municipal wastewater treatment plants, water works and industrial facilities, or fish farming facilities. Our instruments help in drinking and sewage water treatment, during food-production or chemical processes. Thanks to our instruments, it is possible to optimize processing, save energy or other costs, and protect the environment.

All the instruments and accessories on this website are original designs and productions from INSA. We know everything about them, so we can meet the individual demands of our customers, recommend and produce the best solution for each particular application.

We attain precious information through our permanent contact with customers, and we use if for further development and improvement of our products. We pay extraordinary attention not only to analyzers or sensors, but also to - for example - a simple clamp. We want our instruments to be easy and comfortable to install, if you wish to do it yourself. We follow new trends and technologies, so you will be always on the top with our products.
